Description
Technical field
The invention belongs to polymeric material fields, more particularly to fluorubber, preparation method and the profit of primary low-temperature vulcanization
The rubber roller prepared with the fluorubber.
Background technology
Fluorubber（fluororubber）It refer to the synthesis high score bullet containing fluorine atom on the carbon atom of main chain or side chain
Property body.The introducing of fluorine atom assigns rubber excellent heat resistance, inoxidizability, oil resistivity, corrosion resistance and resistance to atmospheric aging
Property, it is widely applied in fields such as space flight, aviation, automobile, oil and household electrical appliance, can not be replaced in national defence sophisticated industry
The critical material in generation.
Vulcanization Process of Rubber is mainly that the crosslinked process that chemical reaction is formed occurs for macromolecular chain.Currently, common fluorine
Rubber formula is required to post vulcanization.Post-cure is the steps necessary in its article manufacturing process.Carry out post-cure
Main purpose be：1）Remaining unreacted crosslinked group after once vulcanizing is set to complete reaction；2）It removes and is generated in primary vulcanization
Cross-linking reaction residue, mainly remove in fluorubber product the water that retains and carbon dioxide and a small amount of fluoride or
The fragment etc. that vulcanizing agent generates.Post-cure can improve the mechanical property and compression set performance of product, reduce product
The gas generated during use, and lower the shrinking percentage of product.Therefore, post-cure has emphatically during vulcanizable fluororubber
The effect wanted.
150 DEG C of vulcanizations can also be used generally at 160 ~ 180 DEG C in primary vulcanization, and post-cure is temperature-gradient method to 250 DEG C of sulphur
Change or is vulcanized using 230 DEG C of constant temperature.Therefore, it consumes energy in fluorubber production process and the time is more.
